SNOW- PLOW.

SPECIFICATION forming part of Letters Patent No. 540,284, dated June 4,1895.

Application filed August 21,1894. Serial No.520,93'7. (No odel.)

To all whom, it may concern:

Be it known that we, WILLIAM J. TREMPER, CHARLES V. Born, and WILLIAM A. Ann STRONG, citizens of the United States, residing in Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Snow-Flows, of which the following is a specification.

This invention relates to improvements in 1 c that class of plows employed for clearing snow from railway tracks, being particularly applicable to street railways and other surface tracks; and the objects of the invention are, first, to provide a plow adapted to throw all the snow on the track to one or the other side thereof or to divide the snow and throw it on or toward both sides of the track, said plow being constructed to be raised or lowered at will, and, second, to provide sideshovels more effective than those in use for throwing orpushing the snow back from the side of a track.

The invention consists in the construction and combination of the various parts, as hereinafter fully described, and then specifically pointed out in the claims.

In the accompanying drawings,which form a part of this specification,Figure 1 is a side elevation of an end of a car provided with a 0 swinging plow formed in one piece and pivoted at the center, the plow being shown in diagonal rear view. Fig. 2 is a top plan view of the plow shown in the same position, the body of the car being removed. Fig. 3 is a 5 special side view of the socket connection of the plow, and Fig. 4. a top view of the same on broken line was of Fig. 3. Fig. 5 is a top plan View of a jointed plow, showing both sections inclined to the rear; Fig. 6, a front view of the joint of the same, and Fig.7 a vertical section on broken line y y of Fig. 5. Fig. 8 is a view of a truck, showing one form of side shovels attached thereto; and Fig. 9, a top view of said shovels. Fig. 10 is a side elevation of a car having a modified form of side shovel attached thereto, and Fig.1l a top plan view of said shovel. Fig. 12 is a top view of a modification in the connection between the main or front shovel and its sup- 5o porting-worm. Fig. 13 is a front view of the parts supporting the bottom of the screw-rod,

the side beams of the car-frame being shown in section. Fig. 14 is a side view of the pivoted connection between one of the tie-rods and the car-frame, the other end of the rod being engaged with one of the brackets H. Fig. 15 is a side View of the connection between the plow and one of struts for bracing the same. Fig. 16 is a front perspective view of the grooved hanger engaged by the sleeve e of the screw-rod.

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A indicates a car-body, A parts of the frame supporting the car body, and A the trucks.

In Figs. 1 to 4 inclusive, 0 represents a vertically movable plow attached to the front of a car, to clear snow from the track. The contour of the lower edge of the plow is waving 7') in outline, the center 0' and the extremities 0 being raised, to pass over obstructions between and on the outside of the rails when theplow occupies its lowered position, and the parts 0 located above the rails, are de- 7 pressed, so as to approach the same as nearly as possible. To the center of the rear face I of the plow is attached an internally threaded sleeve, 0 engaged by a screw'rod, D, having the lower end thereof revolubly secured in a plate, D, and the upper end passing up through the car-platform and carrying a hand wheel, D Plate D is bolted to the lower end of a beam, E, secured to the bottom of the car and extending diagonally downward, the beam being braced by diagonal side struts E, having their lower ends secured to said beam by a strap, 6. Sleeve 0 may engage a vertical slot,f, in ahanger, F, depending from the bottom of the car and braced at its lower end by struts F.

Plow c is moved around screw-rod D, so as to advance and retract its opposite ends, as shown by full and broken lines in Fig. 2 and by turning the screw-rod the plow is also 9 5 raised and lowered. Near each end of the plow is bolted a vertical plate, G, having an inwardly projecting perforated bracket, G, on each end; and to each side of the car is attached a depressed and forwardly eXtend- 10o ing strut, G forming a loop, g, each loop being in position to engage the face of a plate G, between brackets G when the corresponding end of the plow is retracted, the plow and strut being connected by a pin, g, passing through the loop and the perforations in the brackets G and permanently secured to the plow by a chain, 9 Inside of plates G there is a perforated bracket, H, also bolted to each end of the plow. The perforation in the bracket on the advanced end of the plow is engaged by a prong, h, on the free end of a tierod, H, having its rear end pivoted to the carframe as shown at W, Fig. 14. The free end of the tie-rod H not connected with the plow is supported by a hook on the end of a chain, h, hanging from the platform of the car.

In Figs. 5, 6 and 7 is illustrated a modified form of plow. In addition to being operated in the same manner as the plow before described, this plow is divided centrally into sectionsl, I, both of which can be retracted at the same time, as shown in Fig. 5, or one section may be advanced, asillustrated by broken lines 1 and the other end retracted. In this construction, two sleeves, K, K, formed together, are employed for connecting the screwrod and plow. Sleeve K is threaded internally and engaged by screw-rod D in the same manner as sleeve 0 Sleeve K is located in front of sleeve K and is embraced above and below by eyes Z of hinge-straps L, secured respectively to sections I, I of the plow, the parts being hinged on a pin, M, passing throughsleeve K and the eyes of straps L. By the retraction of both sections of the plow an opening or recess, M, is formed at the apex of thetriangle, caused by the retraction of the plow-sections; and this recess is covered by a colter, N, removably secured to said sections. On wings N of the colter are hingepins 01, which engage eyes or sockets m on the faces of the plow-sections and are adapted to be lifted therefrom, as illustrated in Fig. 6.

Fig. 12 illustrates a preferable way of forming a sleeve, P, for engagement with the screwrod.

Figs. 8 to 11, inclusive, illustrate new constructions of shovels for throwing the snow away from the sides of the track after it has been removed from between the rails by the plow.

In Figs. 8 and 9 is shown a double shovel having the outer ends hinged by rings 1' and hooks r to the car-body. Rings r are connected with the ends of ribs 4*, to which the shovels r are secured. The outer ends of the shovels meet and are joined by a hinge-pin, r. The meeting ends of ribs r are secured to the car-body by links W, and the shovels are further connected with said car-bod y by chains 4".

Figs. 10 and 11 illustrateatriangular shovel, T, the meeting points or ends of which are formed together. The ribs of this shovel are hinged to a side-bar, t, of the truck, as shown at 15'. At the apex of this shovel there is a hook, t and to this is attached a chain, 79, passing over a sheave, t and connected with one arm of a bell-crank lever V the free arm V of which engages a rack, V secured to the side of the car, whereby said shovel can be raised or lowered and secured in such raised or lowered position.

It is obvious that many changes may be made in the details of the construction of our snow-plow without departing from theprinciple of our invention. WVe do not limit ourselves to any special connection between the screw-rod and plow in front of the car, nor to the manner of raising the plow by means of the screw-rod, nor to any special mode of hinging the sections of the plow together. Neither do we restrict ourselves to the construction or manner of connecting the parts of the side shovels.

Our improvements involvea radical departure in the construction and principle of operation in snow plows and shovels, the invention consisting, broadly, in a plow pivoted on a screw and adapted to be raised and lowered thereby and in double faced shovels attached to the side of a car and constructed to be raised and lowered.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
